M42 High Speed Steel
M42 is a high-quality cobalt high-speed steel. Its chemical composition is designed for high hardness and excellent thermal hardness. These characteristics make the steel the best choice for machining high-strength and pre hardened steels, high hardness alloys and difficult to machine nonferrous metal superalloys used in aerospace, petroleum and power generation industries.
Cutting tools made of M42 steel can cut iron-based superalloys, cast superalloys, titanium alloys and ultra-high strength steels. Because of its good grindability, it can be used to manufacture all kinds of high-precision and complex cutting tools.

APPLICATION
M42 high speed steel is suitable for manufacturing all kinds of wear-resistant and impact resistant tools for strong cutting, advanced punching dies, screw dies, tools requiring toughness and complicated shapes, milling cutters, drill bits, etc.
M42 Steel Characteristics
M42 steel is a high cobalt toughness high-speed steel mainly used for manufacturing high toughness precision wear-resistant hardware cold stamping dies, cutting tools, and cooling in knives. It has good hardness and thermal hardness, reaching a hardness of 70HRC, while also maintaining a high hardness at high temperatures, making it easy to grind.
The main component of M42 steel is high-speed steel, which contains a high proportion of cobalt element. The addition of this alloy element endows M42 steel with excellent wear resistance and fatigue resistance. When manufacturing cold stamping molds, the high hardness and wear resistance of M42 steel can ensure a longer service life of the mold, reduce the frequency of mold replacement, and improve production efficiency. In addition, due to its high hardness and wear resistance, M42 steel is also suitable for making cutting tools, such as turning and milling cutters. These tools need to have good wear resistance and deformation resistance during high-speed cutting, and M42 steel can meet these requirements.
In addition to wear resistance and fatigue resistance, M42 steel also has good thermal hardness. Thermohardness refers to the ability of a material to maintain its hardness at high temperatures. When manufacturing cutting tools, it is often necessary to perform cutting in a high-temperature environment, which requires the tool material to have good thermal hardness. M42 steel can maintain high hardness at high temperatures and is not prone to softening or losing cutting performance, thus ensuring the stability and reliability of cutting tools.
